"CAR ROOF.

Application filed '.Beptem'ber To all i12/0m it may concur/a.'

Be 1t lrnown that l, lil/Timm: SP. hrnurrrv.,

:a citizen lof the United States, residing in New York, in the county 4of New York Iand State of New York, have invented 1.a new and useful Improvement fin Roofs, of which the following fis :a specification.

'This invention relates to 'improvements in car roo-fs and more particularly to-outside metal roofs comprising a pilumlity of metal sheets, movably mounted on the substructure.

It is the object :of Vthis Iinri-zrntion to enable such roofs 'to accommodate the 'various distortions arising from 'the fraclring :and weaving of :thev'car and to provide flashings pa-uticularly for the ends of the fcair, which will -be `capable of 'relative movement when lthe car lgoes lout of square.

The `invention consists in :the parts zand combination (of par-ts, hereinafter Vdescribed and shown upon the accompanying :dr-afwing, in which.:

Figure l is a plan view o'rf ithe end `,portion of a car roof embodying this invention with parts broken away.

Figure 2 is `an :enlarged detail view .in perspective or'I a side section of the :iinproved end flashing.

Figure 3 is an enlarged detail view in perspective of the central Vsection of thc end flashing.

Figure il is an enlarged detail vic-w in perspective of' a side section 4of .an -end cap.

Figure is an enlarged detail view in section taken on the Aline .of Figure 1.

ln the construction illustrated, the lroof sheets l extending transversely of the car from ridge to eaves, are rebent upon themselves on the under side at the eaves to engage or hook into a side flashing 2 rebent upon its upper side, with the end sheets narrower at the eaves than at the ridge allowing flexibility of the roof to accommodate distortions,

The end flashing as constructed in accordance with this invention comprises three sections. The side sections 3 extending from adjacent the ridge beyond the side flashing 2 lie over and upon the sheathing boards et and side flashing, and are wider at the eaves than at the ridge with inner edges substantially parallel to the edge of the end sheet, under which they extend. Each of these side sections is provided with a flange 5 depending 'over the 1, 1920. Serial No. 407,288.

.end of Lthe 4car with athe eaves lend G 'olf kthc section adjacent the side "flashing nrebent on the under side "to engage or 'hook vinto the side flashing. rEhese sections :are each provided with .la struck up .ri 7 extending substantiallyT throughout :and .adjacent the inner f'edge. The end center flashing coni- ;prises ia Aplate y8 lying `over :and upon the adjacent ends fof the side :flashing sections '3 at Athe ridge, Iextending to lthe struck `up ribs 7 fand :is provided Lwith a depending Vflax-ige y9 `flying over `and vupon fthe flanges 5 of the side sections 3 "on lthe 'end olf the car. The -side sections 3 are snailcd @to the sheathing `boards "between ithe 'inner edge and :the rib 7 with the flange -5 of' fthe Asection and the flange 19 of 4the end fcenter flashing nailed fte the endroit the vcar or end plate l0.

End fcaps are yplaced yover the edges el .the end sheets and are also preferably censtructed .in three sections. The side sections v11 feit the end caps extend :troni adjacent the ridge over the side ofthe car and lie sever and Aupon the lend :roof sheets `extending inwardly with the inner yedge parallel to and terminating short of the inner edge of lthe end flashing 3. Each end ycap section -is provided with 5a flange 19t/depending over the end of ear V'below the flanges 5 'and 9 of the end flashing, :and which nailed to the Yend Yof car or end plato 10, the eaves end of the lend sections being provided with .a .flange .ll-3 depending over and engaging the side plate orf .the car. A center end cap lil covers the space between the adjacent ends of' the cap sections ll at the ridge.

As shownr in the enlarged sectional view of Figure 5 and by the broken away parts of Figure 1, the `struck up ribs 7 of the end flashing 3 are substantially parallel to the end edge of theadjacent roof' sheet l and supports it above the body of the end flashing The end caps l1 extend beyond the ribs 7 and the inner edges 15 are preferably rebent on the under side to lie upon the upper portion of" the end sheet and hold it loosely against the ribs 7 of the end flashing which allows niovernent of the end sheets and at the saine time causes any water that may be blown under the cap to be drained off into the eaves flashing.

The struck up rib 7 not only adds to the rigidity of the inner edge of the end flashing but allows the end roof sheet to re-enter freely should the sheet be pulled out over the rib by extreme Weaving. In such an event the single thickness of the end flashing resting upon the Wood sheathing Will allow the edge of the end sheet to ride thereover and re-enter between the flashing and cap Without jamming, buckling or otherwise disfiguring the sheet.

What I claim is:

l. An end flashing for a car roof comprising sections having portions resting on the end portion of the car and flanges overhanging' the end of' the car, the portion of the flashing resting on the car being provided with a struck up rib extending substantially throughout its length.

2. An end flashing for a car roof comprising sections having portions resting on the end portion of the car and flanges over- V hanging the end of the car, the portion of the flashing resting on the car being provided With a struck up rib substantially parallel to and adjacent the inner edge extending substantially throughout its length.

3. An end flashing for a car roof comprising side sections each resting on the end portion Vof the car and having flanges overhanging the end of the car, the portion of the ashing resting on the car being provided With a struck up rib extending substantially throughout its length, and a center section overlying the adjacent ends of the side sections. v

4. An end flashing for a car roof comprising side sections each resting on the'end portion of the car and having flanges overhanging` the end of the car, the portion of the flashing resting on the car being provided With a struck up rib adjacent the inner edge extending substantially throughout its length, and a center ksection overlying the adjacent ends of the side sections.

5. A metal car roof comprising roof sheets arranged transversely of the car and having rebent eaves portions, side flashings having rebent portions (zo-operating with the eaves portions of the roof sheet, and an end flashing for the car having a struck up rib along its length under the roof sheets, the eaves ends of said flashing being rebent so as to co-operate with the rebent portions of the` side fiashings.

6. A metal car roof comprising roof sheets arranged transversely and having rebent eaves portions, side fiashings having rebent portions co-operating With the rebent eaves portions of the roof sheets, and an end flashing for said car, said end flashing comprising side sections each having a struck up rib along its length and a center' section overlying the adjacent ends of the side sections between the struck up rib land the end of the car.

7. A metal car roof comprising roof sheets arranged transversely of thecar and having rebent eaves portions, side fiashings having rebent portions co-operating with the rebent eaves portions of the roof sheet, and an end flashing for said car, said end flashing coniprising side sections tapering in Width from eaves to ridge, each having a struck up rib along its length, arranged substantially parallel to and adjacent the-inner edge.

8. A metal car roof comprising an end roof sheet tapering from ridge to eaves', an end flashing tapering from eaves to ridge, arranged beneath said sheet having a struck up rib along its length, an end cap for said Y end sheet and end flashing and means for secu/ring said end flashing and cap tothe car.

9. A metal car roof comprising end roof sheets, an end flashing arranged beneath said sheets, said end flashing being madein sections, each side section having a struck up rib along its length and a central section overlying the adjacent endsy of the side sections, said end sheets tapering from ridge to eaves and said flashing side sections tapering from eaves to ridge, end caps for said end sheets and said end flashing having a portion extending beyond the ribs of said flashing side sections and substantially parallel therewith, and means for securing the end sheet flashing and end sheet capsV to the car.
